Answer:
1) A = 4x² + 4x + 1 units²
2) A = x³ + 12x² + 48x + 64 units³
Step-by-step explanation:
1)
A = s²
A = (2x + 1)²
A = (2x + 1) (2x + 1)
A.= 4x² + 2x + 2x + 1
A = 4x² + 4x + 1 units²
2)
A = s³
A = (x + 4)³
A = (x + 4) (x + 4) (x + 4)
A = (x² + 8x + 16) (x + 4)
A = x³ + 8x² + 16x + 4x² + 32x + 64
A = x³ + (8x² + 4x²) + (16x + 32x) + 64
A = x³ + 12x² + 48x + 64 units³
